FYI, I am not (and do not wish to be) the maintainer for the
save/restore/migration/remus code; I'm just an interested party (since
if it breaks, I'm going to have to deal with it when it comes into
XenServer).  As such, my "Ack" was only meant to mean, "I'm fine with
this" (since I had raised an objection before).  IanJ's approval is
still needed for check-in.
